  • Patent number: 6922259
    Abstract: A method for storing data in an electrical storage device associated with a printing component of an ink-jet printing system. The electrical storage device is responsive to printing system control signals for transferring information between the printing component and the ink-jet printing system. The electrical storage device includes a write once portion, a non-protected portion, and a protected portion. The write once portion or the protected portion contain information indicative of a refill ink in the printing component. Installation of the printing component into the printing system enables the printing system to alter information in the write once portion or the protected portion to indicate that the refill ink in the printing component has been used.
